My child has an allergy. Only during sleep, my child develops breathing difficulty and shortness of breath, which disturbs sleep. We consulted an allergist last Saturday. The doctor prescribed Levolin (3 puffs at night) and Budecort (1 puff at night) for one month. After starting the inhalers, my child's breathing at night has improved, but there is still breathing difficulty during the afternoon nap. It has been 4 days since we started the treatment. Should we wait and continue the treatment for some more time, or should we take my child back to the doctor?"
